Answer 1

$\frac{5(3)}{9} +\frac{13}{27} =\frac{15+18}{27} =\frac{31}{27} =1\frac{4}{27}$

$\frac{3(3)}{8} +\frac{5}{24}= \frac{9+5}{24}= \frac{14}{24}=\frac{7}{12}$

$\frac{5(6)}{12}- \frac{13}{72} =\frac{30-13}{72}= \frac{17}{72}$

$\frac{3(7)}{5} -\frac{1(5)}{7}= \frac{21-5}{35} =\frac{16}{35}$

$\frac{5(5)}{12}+ \frac{1}{60}= \frac{25+1}{60} =\frac{26}{60} =\frac{13}{30}$

$\frac{9(8)}{17}- \frac{19(2)}{68} =\frac{42-38}{136}= \frac{4}{136}=\frac{2}{67}$

$\frac{9(3)}{10} -\frac{4(2)}{15} =\frac{27-8}{30} =\frac{19}{30}$

$\frac{4(4)}{15}- \frac{11}{60} =\frac{16-11}{60} =\frac{5}{60}= \frac{1}{12}$
